Toward a new methodology for measuring the threshold Shields number.

Blaise Etienne Marceau Dhont, Gauthier Paul Daniel Marie Rousseau

A number of bedload transport equations involve the threshold Shields number (corresponding to the threshold of incipient motion for particles resting on the streambed). Different methods have been developed for determining this threshold Shields number; t ...

Continuous monitoring of bedload transport in a laboratory flume using an impact sensor

Christophe Ancey, Blaise Etienne Marceau Dhont, Gauthier Paul Daniel Marie Rousseau

Bedload transport rate in gravel-bed rivers shows large non-Gaussian fluctuations, even under steady flow conditions. The development of high-resolution measurement techniques during the last two decades creates research opportunities to study the intermit ...

American Society of Civil Engineers2016

Experimental and field studies have shown how intermittent bedload transport can be at low flow rates. The development and validation of bedload-transport equations require high-resolution records over long periods of time. Two technologies are considered ...

Time Scales, Bedforms and Bedload Transport

Blaise Etienne Marceau Dhont

Bedload transport rates in mountain streams may exhibit wide fluctuations even under constant flow conditions. A better understanding of bedload pulses is key to predict natural hazards induced by torrential activity and sediment issues in mountainous area ...

Rivers in mountainous areas are subject to cyclic perturbations due for instance to summer storms or daily variations in snowmelt. Such phenomena cause successive floods occurring under very similar forcing conditions. However, as shown by several field st ...

Developing methods to assess the extent of naturalized slash pine populations and their habitats characteristics in South East Queensland, Australia

Blaise Etienne Marceau Dhont

Slash pine is an exotic commercial species that is widely planted across South East Queensland’s coastal region. Several studies have observed naturalized slash pine populations around plantations, although there have been minimal efforts to control report ...
